Ok after reading for about an hour I think i have this figured out??
I am looking to buy an 07 fx4 with the 5.4 and 55k miles

The 07 does have some spark plug issues.
Should I ask the dealer to replace the plugs before I buy.
is their a new type of plug that would eliminate these issues

I love this truck but am a little worried about this issue.

Thanks

Um, I am pretty sure that the spark plug issue was straightened out by 2006. I could be wrong.
